Yothu Yindi are an Australian musical group with Aboriginal and non-Aboriginal members, formed in 1986 as a merger of two bands formed in 1985 – a white rock group called the Swamp Jockeys, and an unnamed Aboriginal folk group consisting of Mandawuy Yunupingu, Witiyana Marika, and Milkayngu Mununggur. The Aboriginal members came from Yolngu homelands near Yirrkala on the Gove Peninsula in Northern Territory's Arnhem Land. Founding members included Stuart Kellaway on bass guitar, Cal Williams on lead guitar, Andrew Belletty on drums, Witiyana Marika on manikay, bilma and dance, Milkayngu Mununggurr on yidaki, Geoffrey Gurrumul Yunupingu on keyboards, guitar, and percussion, past lead singer Mandawuy Yunupingu and present Yirrnga Yunupingu on vocals and guitar.

Yolŋu Matha, meaning the 'Yolŋu tongue', is a linguistic family that includes the languages of the Yolngu, the indigenous people of northeast Arnhem Land in northern Australia. The ŋ in Yolŋu is pronounced as the ng in singing.
